### 5. Setup MinIO with OpenID configuration URL

MinIO server expects environment variable for OpenID configuration url as `MINIO_IDENTITY_OPENID_CONFIG_URL`, this environment variable takes a single entry.

```
export MINIO_IDENTITY_OPENID_CONFIG_URL=https://localhost:9443/oauth2/oidcdiscovery/.well-known/openid-configuration
export MINIO_IDENTITY_OPENID_CLIENT_ID="843351d4-1080-11ea-aa20-271ecba3924a"

        bb.position(22);
        bb.put("SINGLE".getBytes(StandardCharsets.UTF_16LE));
        bb.putShort((short) 0);

        referral.decode(testBuffer, 0, testBuffer.length);

        String[] expanded = referral.getExpandedNames();
        assertEquals(1, expanded.length);
        assertEquals("SINGLE", expanded[0]);
    }

    @Test
    public void testManyExpandedNames() {

	None Fault = iota
	MissingContentLength
	TooBigObject
	TooBigDecodedLength
	BadSignature
	BadMD5
	MissingUploadID
)

// Wrapper for calling HeadObject API handler tests for both Erasure multiple disks and FS single drive setup.
func TestAPIHeadObjectHandler(t *testing.T) {
	ExecObjectLayerAPITest(ExecObjectLayerAPITestArgs{t: t, objAPITest: testAPIHeadObjectHandler, endpoints: []string{"HeadObject"}})
}

        }
    }

    @Nested
    @DisplayName("Size Calculation Tests")
    class SizeCalculationTests {

        @Test
        @DisplayName("Should calculate size correctly with single lock")
        void testSizeWithSingleLock() {
            Smb2Lock[] singleLock = new Smb2Lock[] { new Smb2Lock(0L, 100L, Smb2Lock.SMB2_LOCKFLAG_EXCLUSIVE_LOCK) };
